[JSP] Problema pagina jsp in Tomcat
Salve,
ho un problema di visualizzazione di una pagina jsp sotto Tomcat.. Allora, ho creato due jsp chiamati errore.jsp e main.jsp . Quest'ultimo si collega ad una servlet di nome Visualizza. Questo è il main.jsp: Codice:
<html>
<%@ page errorPage="errore.jsp" %>
<%@ page language="java" import="javazoom.upload.*,java.util.*" %>
<jsp:useBean id="upBean" scope="page" class="javazoom.upload.UploadBean" >
<jsp:setProperty name="upBean" property="folderstore" value="/uploads" />
</jsp:useBean>
<head>
<title>Calcolo Trasposta in parallelo</title>
<style TYPE="text/css">
<!--
.style1 {
font-size: 12px;
font-family: Verdana;
}
-->
</style>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>
<body bgcolor="#FFFFFF" text="#000000">
<form method="post" action="main.jsp" name="upform" enctype="multipart/form-data">
<table width="60%" border="0" cellspacing="1" cellpadding="1" align="center" class="style1">
<tr>
<td align="left"><b>Selezionare un file da spedire:</b></td>
</tr>
<tr>
<td align="left">
<input type="file" name="uploadfile" size="50">
</td>
</tr>
<tr>
<td align="left">
Dimensione1: <input type="text" name="dim1" size="4">
Dimensione2: <input type="text" name="dim2" size="4">
Numero processori: <input type="text" name="nproc" size="4">
</td>
</tr>
<tr>
<td align="left">
<input type="hidden" name="todo" value="upload">
<input type="submit" name="Submit" value="Upload">
<input type="reset" name="Reset" value="Annulla">
</td>
</tr>
</table>
<br>
<%
if (MultipartFormDataRequest.isMultipartFormData(request))
{
// Uses MultipartFormDataRequest to parse the HTTP request.
MultipartFormDataRequest mrequest = new MultipartFormDataRequest(request);
String todo = null;
if (mrequest != null)
{
String d1=mrequest.getParameter("dim1");
String d2=mrequest.getParameter("dim2");
String d3=mrequest.getParameter("nproc");
if ((d1!=null && d1.length()>0) && (d2!=null && d2.length()>0) && (d3!=null && d3.length()>0)){
todo = mrequest.getParameter("todo");
if ( (todo != null) && (todo.equalsIgnoreCase("upload")) )
{
Hashtable files = mrequest.getFiles();
if ( (files != null) && (!files.isEmpty()) )
{
UploadFile file = (UploadFile) files.get("uploadfile");
if (file != null)
{
upBean.setOverwrite(true);
upBean.store(mrequest, "uploadfile");
String location="\"http://localhost:8080/ProgettoSDM/visualizza";
location=location+"?file_in="+file.getFileName()+"&dim_1="+d1+"&dim_2="+d2+"&nprocs="+d3+"\"";
out.println("<H1><div align=\"center\"><BR><B><a href="+location+" target=_blank>Visualizza risultato</a></B></div></H1>");
} //if(file!=null)
} //if (files!=null)
else
{out.println("<li>Nessun file spedito");} // else
} //if(todo!=null
} // if(d1!=null)
} //if mrequest!=null
else{out.println("<BR> Non sono stati immessi tutti i dati necessari");}
} // if MultipartFormDataRequest
%>
</form>
</body>
</html>
